CHARLES EDWIN HAMILTON, OF TRQY, YORK.

IRONINQ MACHINE.

Application filed February 1, 1922. serial No. 533,169.

7 '0 a? Z w ham it may concern Be it known that I, CHARLES EDWIN HAMiL'roN, a citizen of the United States, and a resident of Troy, in the county of Rcnsselaer and State of New York, have invented certain new and useful Improve ments in Ironing Machines, of which the following is a specification.

The invention relates to ironing pads as employed in ironing tables for pressing or in an ironing machine; and more particularly to the coils or springs such as are shown in the resilient pad set forth in U. S. Letters Patent No. 1,054,407, granted me the 25th day of February, 1913.

The pad disclosed in said patent consists substantially of a base plate upon which are secured a plurality of adjacent and helically coiled springs, the latter being covered by suitable caps which support a fabric top. In the use of these springs, particularly with pads of inclined or cylin- (lrical shape, difficulty has been experienced in retaining the frictionally held caps to the spring ends; and, when a bottom cap is also employed, of retaining the spring in the said bottom cap. In a co-pending applicatidn for U. S. Letters Patent, Serial N 0. 460,696, filed April 12th, 1921, I have disclosed means for rendering accidental displacement of the caps less likely to occur; but I have since found that, if the coils be constructed in manner hereinafter set forth,

the caps may be entirely dispensed with. In the accompanying drawings which illustrate the invention Fig. 1 is a sectional view of a cylindrical type of pressing machine provided with the resilient ironing pad which comprises springs without any caps whatsoever.

Fig. 2 is a fragmentary perspective view of the improved form of cap.

Fig. 3 is a fragmentary sectional view, illustrating the manner of securing the caps to a base plate.

Fig. 4 illustrates a modification.

Similar characters of reference designate corresponding parts thruout the several views.

I Referring to the drawings, the pad may be of various shapes, for example cylindrical as is illustrated in Fig. 1; and it is this t accordance with the present invention, however, both the base and top caps are eny e of machine that is likely to introduce iiflculty in the use of capped springs. In

tirely dispensed with, the pad being composed of a base plate 10 to which are secured in any suitable manner, for example by means of grommets 11 (Fig. 3), a plurallty of springs 12, the inner edge of a grommet encircling the innermost convolution of a spring. This convolution may be of lesser diameter than the body of the spring, as shown in Fig. 3; or, may be of the same diameter, as shown in Fig. 4'. However, in accordance with the invention, the outermost convolution 13 is reduced in diameter, being of lesser diameter than the body portion of the spring. This will afford a sufiiciently closed surface for supportingthe fabric 14, or the like, over the springs which are staggered and located closely together to afford a proper surface for ironing.

The tapering off of the upper end of the springs thus eliminates the caps heretofore employed; and, similarly, by employing grommets to secure the inner end of a spring. to the base plate 10, the base caps may also be eliminated, thus facilitating assembly of the pad as well as reducing the cost thereof and obviating the objectionable feature of the spring becoming separated from its caps.

1. A unitary resilient supporting member for use with an ironing pad, comprising a supporting base plate, and a plurality of springs rigidly secured at one end to the plate over the surface thereof, the other end of the springs being free and adapted to support the pad.

2. .In an ironing pad support member of the character described, a base plate, and a helically coiled spring having its innermost convolution of lesser diameter than the body of the coil and secured to the base plate.

3. A support member for an ironing pad of the character described, comprising a perforated base plate, a helically coiled spring registering with a perforation thereof and having its outermost convolution of lesser diameter than the body of the coil to receive and support the pad, and a grommet passing thru the perforation to secure the innerniost convolution of the spring to the base ate. p 4. A support member for an ironing pad of the character described, comprising a base plate, a helically coiled spring having its at the top outermost convolution of lesser diameter than the body of the coil to receive and directly support the pad and its innermost convolution secured to the base plate.

5. A support member for an ironing pad of the character described, comprising a base plate, a helically coiled spring having its outermost convolution of" lesser diameter than the body of the coil to receive and directly support the pad and its innermost 10 Signed at Los Los Angeles and 23rd day of 'J an Angeles in the county of State of California this uary'A.
